The intehet wheel is ievoluhly mounted i in ai. l'iznne --i and is operated hy any Suitable I sourire ol' power, such, for instance, ns clocki work 5. For the purpose of arresting the wheel 3, it is provided on hoth'fuees with a, l ring` of enteh teeth (i :ind 7, while in :i posil tion of repose ti new! 8 engage',v with the toet h o und therein' stops the wheel 3 in the i position of reposo.

This extends up to henenth ai bridge piece lwhich is vertienlllv diSpl-.Leenhly nitimnted on pins 1:; (Fig. e).

The bridge piece under the :ic-,tion of a .4px-ing ll umd is nehed downwind by pins, 15 whieh nre infini) `connected with the keys i l (Fig. 7), Non' 'Hf a. key he operated, its pin 15 presses hnek the hridge lli, which in llni'n pienses heel( the pnwi ftinit is to say, i relensen the wheel 8. The hitter esi-nA 110W tnx-nv In order to stop the wheel 3,. lifter a the rimpel-tive depresod key, n pnwl 16 is rovided which is adapted to engnge in the teeth 7, This ptiwl 16 is pivotod on the axis 1T of the wheel nnd is returned hy n. spline 1R into n nomini position. Further the pawrl lo is pivotzil on n horizontal pin 1Q and hears, with :in extension or prolongation, against the hridge l2, so that it disoends with the l hitter :ind eonies into engagement with the f teeth T. Now if thix wheel 3 he released, it l turns together with the pnwl 1 until the l lknt'ter eneounters the pin 15 of the depressed 'ey l.

The movement is also so calculated rot zition corresponding to the igui'e value. of

from the imn'ie, certain partis ol" the .shifting i an index or pointer 21 and by the hel of a tablet 22 in( icates the adjusted calcu atin operation. This lever is formed as a crank lever and is pivotal on a bolt 23 of the frame 4. With its free arm it engages a disk 24 of a gear or driving mechanism 25 which is displaceably mounted on'an axis 26 which transmits the rotary motion to the first inion 31 of the calculating mechanism 2 igs. and 11). ,Other pinions or gear wheels 28 and 29 are displaceably arranged on a second spindle 27, which wheels are moved simultaneously with the wheel bymeans of a friction disk 30 fast'on the pinion 25. The pinion 28 is in constant gear with the pinion 25, While the pinion 29, for instance, enga es with the ratchet wheel in the position or subtraction. The direction of rotation of the spindle 26 is thus altered acco ding as the w eel 3 is in engagement with the pinion 25 oi' the pinion 29.

The spindle 16 carries a pinion 31 which drives the calculatinghmechanism as follows: Iinion 31 meshes wit a pinion 32 on a spindle 33 carrying a tooth 37 adapted, once in each revolution of spindle 33, to turn a pinion 38, loosely revoluble4 on a spindle 38', one-tenth of a revolution; the pinion 38 meshes with a pinion 39 fast on a spindle 40 which carries a tooth 43 adapted, once in each revolution of spindle 40, to turn a pinion 44, loosely revoluble A,on a spindle 44', one-tenth of a revolution ;4 the pinion 44 meshes with a pinion 45, loosely revoluble on a s indle 45'.l The s indle 33 and 40 carry dis 34 and 41 on w 'ch are figures, from 0 to 9, which ma 'be read through the openings and 42. A ove the openings 35 and 42 1s arranged to move laterally, a s lide 48 pro i vided with a horizontal row of apertures 48.

ln this slide is journaled on the spindles 47 a series of pinions 49', 49, 493, 494, 495, ete.,

f which carry disks 46 on which are numerals from O'to 9; the pinions 49, 49, etc. are not co ected with each other and are designed td be turned only when they mesh with the pinions 32, 39 and 45.'

It will b e obvious that with a mechanism comprising the arts 26, 31, 32, 33, 3"?, 38, 39, and the isks 34 and 4l, each time a key 1 is pressed, the spindle 26 will rotate a distance corresponding to the vlaue of the key: that, furt 'er once in every revolution of disk 34, disk 41 will i'otatr onc-tentli of a revolution. ln this wa any amount up to 99 may be added. Subtraction will be accomplished in substantially the saine way, dle 26 and the train of mechanismwliic it controls will rotate in the reverse direction. The purpose of the slide 48 and the mechanism carried thereby is to facilitate the calculations. At the` openings 35 and 42 the operator; needs to watch only the two right hand figures of a sum as the calculation roceeds. As each column of ligui'es is ad ed, and before starting to add the next column, the slide 48 is shifted to the right so that, for instance, instead of pinion 49 meshing with inion 32, pinion 49z will now mesh with pinion 32, while pinion 498 will mesh with pinion 39; the slide is shown in the new position in Fi 14. Thus assuming we have a column of igures, say, 63, 73, 44, 37 and 42, the slide being in its ini ial position and all the disks showing U, upon adding 8, 3, 4, 7 and 2, 24 will app r at the o enings 35 and 42, and also at t e first an second right hand openings 48 in the slide. The slide is now moved one oint to the right and the next .column of gures 6, 7, 4, 3 and 4, is added. At the openings 35 and 42 will now appear 48, but at the three'i'ight hand openings in the slide will a pear 264, which is the sum of thenumbers wlhich were to be added. Each time a fresh column is to be added the slide is moved one point to the right. Ordi narily, a column of figures will not total over 99, so that two openintgs 35' and 42 are sufficient; the machine o `course may be constructed with three or more such openings and corresponding mechanism to accommodate columns-*oi fi rures which would total over 99. 'Ilhe num er of the keys 1 and the figures may of course be any suitable one, so that suitable' calculations may be carried out.

Preferably the entire ap aratus is4 inclos in a box with a lid adapted to lift up, so that the apparatus is protected.

I declare that what I claim is:-

1. In a calculating machine, the combination, with a. suitable support and a suitably driven rotary part normally actuated to rotate in a given direction, of a rectilineally movable device normally acting to restrain said art against rotation; a rectilineally movable member movable against said device to cause the same to release, the rotary part, rectilincally movable keys held normally spaced from said member but movable against the saine to actuate it, and a fulcrumed part normally drawn in a direction opposite to the direction of rotation of said rotary part and movable between the same and the ke` s, said fulcrumed part having a ratchet-an -pawl engagement with the rotary pgrt, substantially as described. i` 2. a calculating machine, the combinaexcept that, lever 2U being shifted, the s intion, with a suitabfe support and a suitably l driven rotary gert normally actuated to rotate in a given ireetion and having a toothed periphery, of a device normally acting to restrain said part againstV rotation, a sliding member movable against said device to cause l the same to release the rotary art, keys held normally s aced'from said idin;r member but movablie` against the same to actuate it, a fulerumed part normally drawn in a direction opposite to the direction of said rotary art and movable between the same and the veys, said fulerumed part having a ratchetand-pawl'enggement with the rotary part, a. calculating mechanism, means, comprising intermeslnng toothed rotary devices movable together axially and allemately engageable with said rotary part and one of them being constantly engaged with the ralculat\ RICHARD BUERK.
